Draw magnetic field lines around a bar magnet.

The magnetic field lines around a bar magnet extend from the north pole to the south pole, forming closed loops. These field lines indicate the direction a small north magnetic pole would take if free to move in the magnetic field. The key features of the magnetic field around a bar magnet include:

1. Outside the Magnet:

The magnetic field lines emerge from the north pole and curve outward into the surrounding space.
They then curve back towards the south pole, completing the closed loop.

2. Inside the Magnet:

Within the magnet, the magnetic field lines follow a similar pattern, curving from the south pole to the north pole.

3. Density of Field Lines:

The density of magnetic field lines indicates the strength of the magnetic field. The closer the lines are to each other, the stronger the magnetic field in that region.

4. Uniform Distribution:

The field lines are evenly distributed around the magnet, demonstrating the symmetry of the magnetic field.
